To all whom it may concern.:

Be it known that I, ROBERT E. RAwLs, a citizen of the United States, residing at Hattiesburg, in the county of Perry and State of Mississippi, have invented a new and useful vWagon Standard., of which the following is a specification.

This invention relates to wagon standards and its object is to provide a simple, durable and inexpensive device of this character which can be readily fastened to a bolster of a wagon and which can be readily extended and held in extended position without employing any special locking means separate therefrom.

Another object is to provide a standard of this character so formed and mounted as to prevent dirt, etc. from accumulating therein and interfering with its proper operation.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a view partly in section and partly in elevation of a wagon bolster and showing two vof the improved standards secured thereto, one of the standards being extended. Fig. 2 is an enlarged longitudinal section through the standard. Fig. 3 is a detail view of the inner or movable member thereof.

Referring to the figuresby characters of reference, A designates a bolster having openings a bored .from the top to the bottom of the end portions thereof. Each bore is designed to receive the fixed tubular member 1 of the standard, said member being formed of a length of metal pipe and secured in place by a bolt 2 extending transversely through the lower end portion thereof and also through the bolster. This bolt constitutes a stop for the inner or movable member 3 of the standard which is also formed of a length of metal pipe of less diameter than the member 1 and which is cut inwardly from its upper end along converging lines as indicated at 1 to form a tongue 5 which is rolled outwardly and downwardly and constitutes an eye for the reception of a ring 6. Formed longitudinally within diametrically opposite portions of the member 3 are slots 7 through which extends a bolt 3 projecting diametrically through the member 1 and constituting means for fastening a brace 9 to said member 1. This brace is bolted or otherwise fastened to the bolster as shown in Fig. 1. The lower end of each slot 7 has an L-shaped lateral extension 10 forming a socket 11 which extends upwardly within the member and is designed for the purpose hereinafter set forth.

Itis of course to be understood that both of the members of the standard are open at their ends so that any dirt or other material which might drop thereinto will promptly pass outward through the lower end of the standard and through the passage a, thus preventing any interference with the operation of the device. When it is desired to extend the standard the inner member 3 is drawn upwardly until the bolt 8 assumes a position within the lower or enlarged ends of the slots 7. Said member 3 is then given a partial turn in one direction so as to bring the sockets 11 above the bolt 8 whereupon member 3 is allowed to move downward so that the bolts will be seated within said sockets. Member 3 will therefore be suported and can not be lowered unless it is rst raised and partly turned so that the bolt` 8 will be removed from the sockets 11. By providing a cross bolt 8 and two slots 7 two bearin s are provided for the member 3 when raised so that the same is firmly supported. As the bolt is fastened at its ends and the member 3 rests thereon between the ends, there is no danger ofthe bolt giving way under any downward. pressure exerted thereagainst through member 3. Moreover, this bolt has the additional function of acting as a securing means for the braces 9.

It will be seen that the standard as herein described is very cheap to manufacture inasmuch as both members are formed of stande ard sizes of metal pipes.

The standard' can be readily secured to a bolster and when so positioned will be both efficient and durable.

What is claimed is:

The combination with a bolster having an aperture extending therethrough; of a tubular relatively 'fixed standard member having open ends and secured within the a erture, a brace secured to t'he bolster and apping said member, a securing bolt extending through the brace and member, a relatively movable tubular standard member having open ends sldably mounted within the Xed member7 said movable member havin oppositely disposed longitudinal slots tIirough which the bolt projects7 said slots terminating at their lower ends in oppositely directed extensions constituting sockets, said sockets being disposed to receive the bolt to support the movable member in elevated position, a tongue rolled outwardly from and integral 10 with the upper end of the movable member and constituting an eye, and a ring mounted within the eye.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
